Scanning the QR code at the turnstiles
All adults must have their own mobile ticket on their smart phone, unless a member of the party requires assistance due to disability. Juniors (15 and under) do not have to have their ticket on their own mobile phone, but must enter with a parent or guardian who has the Junior's ticket on their phone.
Limits on the multiple mobile tickets
There is not a limit on how many tickets you can hold in your app, although you may be restricted on how many you can purchase per event.
